ABDOMINAL TBUSS.

Application filed May 3, 1918.

To all whom it may concern:

Be it knOWn that I, EDWARD ALEXANDER NELSON, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Abdominal Trusses, of which the following is the specification.

My invention relates to improvements in abdominal trusses and the obj ect of the invention is to devise a truss which will snugly fit the body, hold firmly in place and conform to every movement of the body without the employment of straps or other means passing through the crotch of the leg or otherwise in contact with the body which would cut into the flesh and also to provide a truss which can be easily cleansed and which will, therefore, be sanitary, which will be adapted to hold various sizes and shapes of pads which may be readily interchanged and which are so formed as not to tend to press upon the rupture but which will hold it together and aid it to heal and generally to provide a truss which may be worn with comfort both by day and by night and it consists essentially of the following arrangement and construction of parts as herinafter more particularly explained.

Figure 1, is a general. perspective view of my truss showing it applied, the position of the body in relation thereto being indicated by dotted lines.

Fig. 2, is a diminutive side view showing the position of the truss upon the body.

. Fig. 3, is a perspective detail of the main truss member.

Fig. 4, is a perspective detail of my pad.

Fig. 5, is a perspective detail of the metal covering plate.

Fig. 6, is a perspective body support.

Fig. 7, is a perspective detail of the pad body.

In the drawings like characters of reference indicate corresponding parts in the various figures.

1' indicates the main truss member which is formed of resilient metal, the center back portion of which is curved downwardly in at 1", such loop being bent slightly inwardly toward the apex 1' of the loop so that it grips and compresses the fleshy portion at the back of the body 111 Specification of Letters Patent.

, 1 are provided detail of the pad 8, is an enlarged sectional detail against Serial No. 232,354.

the position indicated in Fig. 2. The side members 1 extend from each side of the loop 1 around the fleshy portion of the hips slightly below the hipjoint, the front portions of such side members inclining downwardly in a general direction substantially parallel with the groin of the patient. The extreme forward ends of the side members with slightly inturned 0&- set portions 1 terminating in a loop 1 The ends of the loop approach each other, the free end thereof being turned outwardly at 1 in an arc-shaped direction with the concaved portion of the are facing outward.

2 indicates a'pad support,-which is provided with a surrounding rabbet groove 2* into which the loop 1 fits. 2 indicates an orifice formed in the center of the pad support. 3 indicates a pad which is preferably formed of felt and provided with a fiat face. The back of the pad fits against the pad support 2, the whole being covered with a covering of chamois leather 4, the chamois leather being folded over the pa 3 and pad support 2 to the back of the pad support, the edges of the. chamois being drawn together and secured by suitable lacing 4?. When in this position the pad and pad support are forced into the loop 1* so that the loop springs into position within the rabbet groove 2 as clearly indicated in Fig. 8. The center of the outer face of the pad support 2 is provided with a rectangular recess 2 into which an internally threaded nut 5 fits thereby holding the nut from turning.

6 indicates ametal covering plate which fits against the outer face of the loop 1, that is, against the. opposite face of the loop to the pad support 2. Theplate 6 is provided with a central orifice 6 and an edge notch 6 through which the out-turned end 1 of the loop 1 extends. 7 indicates a screw which passes through the orifice 6 and is threaded into the nut 5 thereby securing the parts together and the pad to the loop 1.

It will, of course, be understood that any form or shape of pad may be used other than that shown in the drawing. For instance, for certain patients where the rupture is large it is necessary to use a large circular pad. In this case the outer portion of the pad support 2 is formed circular and a projecting portion extends therefrom corresponding in shape to the outer portion of Patented Feb.11,1919.

thereby holding the position by means the pad support indicated in Fig. 6 which fits into the loop 1 in a similar way.

The member 1 may be provided with "a covering of rubber tubing 8 as indicated in Fig. 1, thereby rendering it more comfortable. The member 1 is sprung around the body of the wearer into the required position, the spring of the metal holding it in place. A connecting strap 9 is then provided with-eyelets 9 through which the outturned portions 1 of the loop 1 extend, parts together. It will beobserved, however, that the strap 9 is outside of the pad and that, therefore, it does not (come in contact with the bodyand .does not tend to injure the :same. When the truss is in position the spring of the metal has a tendency to have an upward inward pull upon :each of the pads, the back portion of the truss being held down in of the lower slightly inturned portion 1" .of the loop 1 gripping the flesh .of the wearer.

It will thus iberseen that in a truss such as have devised the springof the metal will yield in any direction allowing any movement .of the body and yet reason of its ,grip on the, 'iiront and back portions of the body there will b07110 tendency for the pads to workout of place orfor the truss to work upward ordownwardly out-ofplaceso as to he uncomfortable or in any way .get out of its correct position.

The resilient loop 1* serves to not only allow of the truss conforming to bodies of various sized persons within certain limits butalso tends to hold the side portions of the trussttogether so that they ,grip the fleshy portions 01 the body below the hip joint r urther serving to hold the truss in place. Also in myconstructionof ,pad '1 have provided a pad with a fiat face which is ;pref- 'erableover a pad having a rounded faceas is usually employed. It -will be readily understood that a pad with a rounded-cream vex .iace hasa tendency to ,press :into'the rup tureand spread .it apart thereby increasing its size, whereas, y .pad being a flat pad tendsto firmly holdtherupturein placeand .to .aid any tendency that there is .for the rupture to heal.

.In my construction of ,trussalso it will .be readily seen that .I have dispensed with all straps or other securing -means extending around the 'bodyfor through the crotch. of the wearer which would have a tendency tocut .into the .fiesh and thereby render :the flesh [sore {and the truss very uncomfortable .to wear.

It will also heseen that SllQhfiAtIllSSfiS I have devised is very compact presenting .no bulky parts and .fits the body so snugly, closely .and (comfortably that .it can be worn :at any time either by .night or day vday and 5 (atthesametimelhave providedapad which 'ber having a loo may be readily disassembled, the chamois being removed with the pad and the chamois firom the pad so that -'lootl1 be thoroughly cleansed thereby rendering the device absolutely sanitary.
